Hey guys, I have an older computer, E-machine model EL1852G-52W, (slim build) being as such it has a hard time keeping up with the games I like to play. What I would like to know is, what can I do to upgrade my computers performance? What can I do in terms of ram, or a better CPU? I do have installed right now a Nvidia GeForce GT730 GPU, and am looking into a better power supply as well, I realize I am probably better off getting another computer, but it isn't in the cards right now, can you help a guy out? I can spend between 300-$500.
